Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all? To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That’s why dry deserts everywhere are almost not covered by trees or grass. Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in. Another thing plants must have before they can grow is food.  What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

1.According to the passage, plants need ______ things to grow well.

A.two         B.three        C.four                 D.five

2.What does the underlined word "cracks" mean in the text?

    A.縫隙          B.表面        C.夾層                   D.底部

3.From the passage, we can know it is _______for plants to grow in dry places.

      A.easy             B.difficult            C.impossible    D.important

4.The reason why most plants can’t grow on the sandy beach is that _______.

    A.there isn’t enough sunlight               B.there is too much water

    C.it is too crowded there                 D.it has little food for plants

5.The passage can most probably be found in a ______book.

    A.science                 B.history           C.travel          D.math

Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more  and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic(遺傳的) material. Foods from plants grown in this way are called genetically modified(改變的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice is being prepared , for example , which stops people becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are,. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural.

【小題2】What are the good things about GM foods  ?
A. They make plants strong against diseases.   B. They are unnatural.
C. They can help in human diseases.            D  Both A and  C.
【小題3】GM foods        .
A. are a quick way to produce food    B. grow in the wild 
C. are safe                           D are grown only in rich countries
【小題4】Why do some people not like GM foods?
A. They are not useful.       B. They are not helpful.
C. They are not natural.      D  They are not cheap.
